Basil Rajapaksa, a brother of President Mahinda Rajapaksa, arrived in New Delhi on Thursday on a short visit to India to interact with Indian leaders as well as officials on issues of bilateral interest.

According to official sources, Khurshid welcomed Sri Lanka's decision to hold elections to the northern province, where for years the Tamil Tigers held sway.

The Indian minister emphasized the need "to fully implement the provisions of 13th amendment and to go beyond it so as to ensure meaningful development of Sri Lanka.

"He urged Rajapaksa not to do anything to dilute the provisions of the 13th amendment."

The India-backed 13th amendment to the Sri Lankan constitution was carried out to ensure autonomy to the country's provinces, and thus allow the minorities to enjoy autonomous rule in the northern and eastern provinces.

The Sri Lankan leadership had repeatedly assured India and the US when the war raged that it would implement the constitutional provision.

But after crushing the Liberation Tigers of Tamil Eelam in 2009, Colombo has gone back on its commitment, casting a shadow on India-Sri Lanka ties.

This is the second time within a month that India has gone public with calls to Sri Lanka not to dilute the 13th amendment, now a deeply divisive subject in the island nation.

Indian Prime Minister Manmohan Singh recently told a group of Tamil leaders from Sri Lanka that he was dismayed by reports that Colombo plans to go back on its earlier promise to stick to the 13th amendment.

Basil Rajapaksa, who is the Sri Lankan minister of economic development, also met Indian National Security advisor Shivshankar Menon and foreign secretary Rajan Mathai Friday.

According to the sources, Rajapaksa expressed his appreciation for the vast number of projects being undertaken by India in Sri Lanka's north and east following the end of the separatist conflict.

Rajapaksa said there was "great appreciation" in Sri Lanka for the projects undertaken by India, especially related to building of houses for those displaced by years of conflict.
